PUNCHlNG-MACHINE.

SPEGIE'IGA'IION forming of Letters Patent N 0. 676,242, dated June11,1901.

Application filed June 15. 1900.

To all whom, it may concern:

Be it known that I, GEORGE M. ROGERS, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedPunching-Machine, of which the following is a full, clear, and exactdescription.

The purpose of the invention is to provide a simple, novel, effective,and durable con-' struction of punching-machines or machines adaptedtoindicate upon a dial or a like device the force of a blow manuallydelivered to a member of the machine.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi catecorresponding parts in all the figures.

Figure 1 is a perspective view of the ma chine. Fig. 2 is an enlargedvertical section through the main casing of the machine, illustrating inside elevation the normal position of mechanism contained in the saidcasing. Fig. 3 is a further enlarged View indicating a sectionthrough aportion of the main casing and a side elevation of the mechanism at thelower portion of the casing-namely, the mechanism which is directlyoperated upon by a blow delivered to the proper member of the machineand the coin-receiving mechanism. Fig. 4 is a vertical central sectionthrough the parts shown in Fig. 3, illustrat ing the indicating-lever indotted lines and in operating position. Fig. 5 is a horizontal sectionthrough a portion of the main casing, illustrating in plan View themechanism contained therein, the coin-receiving chute be log inhorizontal section; and Fig. 6 is a vertical section through a portionof the main casing, taken at the rear of the mechanism contained in thecasing and showing in rear elevation the mechanism contained in thelower portion of the casing.

In the organization hereinafter described the apparatus is shown as acoin-controlled apparatus, in which the device is rendered operative bythe insertion of a coin. I do not Serial No. 20,424. (No model.)

claim such coin-controlled features in this case, nor do I limit myinvention to such coincontrolled parts, as it will be obvious that theparts which are set into operative relation by a coin may be definitelyadjusted to such operative relation by an extension of one of theseparts to such position as to be within reach of definite adjustment byhand without the use of a coin.

A represents a main casing in which the operative parts of the machineare contained, and this casing may be placed upon a pedestal B or may beotherwise supported. A'dial 10 is fixed in the front face of the maincas- 63 ingA and a scale in pounds and fractions of pounds is producedupon the dial. A'pointer 11 is adapted to travel over the face of thedial 10, and this pointer is secured to one end ofa shaft 12, whichextends within the main 7o casing A and is journaled in thedownwardlyextending members 13 and 13 of a hanger 13, attached to theupper wall "of the casing A; but the form of hanger 13 may be changed,if desired. The shaft 12 between the members of the hanger 13 isprovided with a pinion l4, the'teeth whereof engage with the teeth of arack 15, formed at the upper end portion of a rod 16, which rod ispassed through an aperture in a foot 17, made at the bottom of So thelonger member 13 of the hanger 13, as is also shown in Fig. 2. A collar18 on the rod 16 limits the upward movement of the said rack and rod;but this collar 18 may be simply employed to connect the rack with therod 16 when this portion of the device is made in two parts. A weight 19is secured upon the rod 16 below its bearing 17, and the lower end ofthe rod 16 terminates in a head or enlargement 20, which is adjustableupon the 0 rod. The weight 19 renders the rod 16 operative in a downwarddirection by gravity; but if the lower end of the rod l6 is unsupportedthe rod 16 naturally drops downward until the upper portion of the rack15 is brought in engagement with the pinion 14. A friction-roller 21 isemployed as aguide for the rack 15, as shown in Fig. 2. The lower end orhead 20 of the rod 16, however, is constantly supported by engagementwith the horizontal table member 22 of an angle-lever O, and in theconstruction of this lever O a leveris in its normal position.

base29.

vertical body member 23 is employed, to which the table member 22 isattached, and a lower horizontal member 24 is likewise employed, whichextends rearward or in an opposite direction to the upper or tablemember 22, together with a vertical terminal member 25, which lattermember has an opening 26 produced therein, as illustrated in Figs. 4 and6. The various parts of the lever (J may be integrally formed. The saidlever at its body portion is pivoted by a pin 27 or its equivalentbetween the upper horizontal members of angle-standards 28,'whichstandards are secured to a base-plate 29. The upper or horizontalmembers of the standards 28 extend in a forward direction; but the formof the standards maybe changed, and preferably the rear lower member ofthe lever O is at the rear of the standards 28 when the (Shown in'Fig.4.) The base 29 may be attached directly to the bottom of the casing A;but in the drawings it'is illustrated as secured to a block 30. Thelever O isheld in its normal position by a spring 31, attached to theforward face of its rear vertical member 25 and to an upi right 32,formed at the front portion of the This spring 31 serves also to returnthe lever O to its normal position after it hasbeen given an inclinedposition, (shown in diottedlines in Fig. 4,) in which latter po-' sitionthis lever O is placed when a plunger, tobe hereinafter described, isoperated by a blow after a coin has been duly deposited in the machine.

At a convenient point in front of the main casing A an opening 33 isformed, which opening ispreferably circular, and a socketplate 34 isadapted to slide in the opening 33,

conforming to the contour of said opening. This socket-plate receives apad 35, which may be termed a punching-head, since the blows of a personexercising are directed against said pad. The punching-head consists ofa suitable cover or casing of flexible material attached to thesocket-plate 34, the space between the socket-plate andinner surface ofthe cover being filled'with hair or other suitable material; but inaddition to such filling a coil or spiral spring 35 is placed within thesaid head, preferably at its cen- 'ter, the spring having-bearing.against the socket-plate, and the outer end of the spring is preferablymade to terminate short of the. striking-surface of the head, as shownin Fig.

' 4. More than one spring may be used, if desired, and the object ofintroducing a spring orsprings in the punching-head is to render lessliable to injure a persons hand wheif forcibly striking the-head.

The punching-head and the socket-plate are guided and prevented fromturning by attaching to the inner face of :the-socket-plate 34:pins orprojections 36, which enter and have movement in slots 37, horizontallyproduced in horizontally-located guides 38, attached to the inner frontwall of the main casing A. A plunger 39 is secured to the centralportion of the inner face of the socketplatefor the punching-head. Thisplunger has free movement in openings made in the front upright 32 onthe base 29 and in arear upright 40, located between the standards 28,and when the lever C is in its normal position the rear end of theplunger 39 will pass freely through the opening 26 in the rear lowermember 25 of the lever O and the said lever Will remain unaffected bythe action of said plunger, so that until certain conditions arecomplied with the punching-head may be struck any number of timeswithout accomplishing any results or moving the lever 0. Therefore thepointer of the dial under such circumstances will remain inactive, sincethe pointer is brought into operation only when the lever O is actedupon by the plunger 39. A spring 41 is coiled around the plunger 39,having bearing preferably against the inner face of the socket-plate forthe plunger-head and the front upright 32 of the base 29.

A curved arm 42 is secured to one longitu dinal edge of the rearmember'of the lever C. This arm extends in direction of the front of themachine and its upper surface is concaved. The arm is guided in itsmovement by engaging with a segmental plate 43, secured to the outerface of one of the standards 28., as shown in Fig. 3. A brake or lookingbar 44 is used in connection with the curved arm 42. This-brakeorlocking bar is pivoted near its lower end upon the outer face of saidstandard 28, as is also shown in Fig. 3, and the lower end 45 of thebrake or looking bar is curved. The rear lower corner of this brake orlooking bar rests upon the upper surface of the curved arm 42, hearinglightly thereon when the various parts are in their normal position; butwhen the lever O by a blow is forced to the inclined position (shown indotted lines in Fig. 4) the lower end of the brake or locking bar willhave such positive engagement with the upper surface of the curved arm42 that it will prevent the lever 0 being restored to its normalposition until the said brake or looking bar is carried out of saidpositive engagement with the arm 42. A spring 45 serves to hold thebrake or looking bar 44 in operative position. When curved arm 42 goesback, itslides freely under the curved lower end 45 of the lockingbar44; but in any tendency of arm 42 to return,'the spring 45 causes lowerend 45 of bar 44 to dig into the curved arm 42, holding it like adetent-brake. Thebrakeis removable from the curved arm 42, and suchresult is obtained usually in the f ollowing'manner: A shifting bar 46is pivotally mounted upon a bracket 46, secured near the upper end ofone of the standards 28, as shown in Fig. 3, and this shifting bar'atitsinner end engages with the rear upper edge of the brake or lookingbar 44, and when the outer end of the shifting bar 46 is carriedrearward the ointed en a in member of the brake or b b b locking bar 44will be carried rearward, and the spring 31 may then act to restore thelever 0 to its normal position. The shifting arm or bar 46 may beoperated from the exterior of the machine by pivoting a rod 47 to theblock 30, for example, and causing the said rod to engage with theforward edge of the outer end portion of the shifting arm or bar andpivoting the rod 47 at its upper end to a connecting-bar 48, whichextends out at the front of the machine, terminating in a knob 49, ifdesired. Thus after a blow has been delivered and the force of the blowhas been indicated on the dial, if another blow is to be delivered, theconnecting-rod 48 must first be pressed inward to permit the lever toresume its normal position and a second coin must be introduced into themachine before the force will be again indicated on the dial. Theconnecting-rod 48 is provided with a suitable spring 50, which serves tocarry it outward after it has been pressed inward and released.

The coin when used is introduced through a suitable slot 51, which maybe at the front of the machine, as illustrated, and the upper end of achute 51 connects with the slot 51, receiving the coin placed in suchslot. The chute 51 is provided at its bottom, which is open, withopposing longitudinal slots 52. (Shown best in Fig. 6.) A pin 56 extendsinto the slots 52, which pin is secured toa shank 53, and a plate 54 isattached to the shank at an angle thereto, as is likewise shown in Fig.6. This plate serves as a gate and isused to close the opening 26 andreceive the plunger 39 when a coin has been placed in the machine andthe punching-head 35 is struck; but in the absence of a coin the gateuncovers the opening 26 sufficiently to permit a free passage of theplunger 39 through it. Thus the punching-head may be struck withoutinjury to the parts of the machine at this time and no record of theblow can be obtained. When the machine is to be organized to be operatedby other means than by a coin-controlled device, it will be obvious thatthe plate 54 must be adjusted by hand in front of the path of theplunger by an extended handle, or there may be no slot through the lowerend of the tilting elbow-lever, so that the plunger will act against itat all times.

Normally the shank 53 is in a horizontal position and the plate or gateis in a downwardly inclined position, uncovering the openingsufficiently to permit the plunger 39 to freely pass through theopening, as has been stated. The gate and its shank are balanced intheir normal position and are pivoted upon a projection from an edge ofthe lower member of the lever O, as is illustrated in Fig. 6, and in thesame figure it will be observed that the downward throw of the gate islimited by a stop 55. When a coin has been received in the chute 51 itwill rest upon the pin 56, and the weight of the coin will carry thegate upward, whereupon the gate 54 will cover the opening 26 in the rearportion of the lever O, and when a blow is delivered upon thepunching-head the inner end of the plunger 39 will strike the gate 54and will force the rear member of the lever O outward or rearward, as isshown in dotted lines in Fig. 4, and at such time the rod 16, operatingthe pointer 11, will drop downward, following the descent of thetable-section 22 of the lever G, and will cause the pointer 11 toindicate on the dial in pounds and fractions thereof the force of theblow that was delivered. The next operation is to press in theconnecting-rod 4S and permit the lever C to assume its normal position.The coin will drop from the chute 51 as soon as the blow is struck, asthe gate is carried back with the lever C and the pin 56 leaves the slot52 at that time, returning to its normal position again after the blowhas been delivered.

In my invention it will be seen that the blow struck on the pad has nodirect influence upon the indicator-hand, but merely adjusts anintermediate devicethe lever C to a greater or less degree ofdeflection, according to the force of the blow, to which position it isheld by a locking device, and which lever G acts as a stop device todetermine the drop of the rod which is connected to and operates theindicator-hand.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a punching or striking machine, the combinationof an indicator-hand, a droprod for moving it from gravity, a movablestop device for limiting the range of movement of said drop-rod to anyvariable point in its fall, a rectilinearly-moving punchingplungeracting upon the movable stop device and directly driving it to avariable position according to the strength of the blow, said movablestop device being arranged between the plunger and drop-rod, and alocking de vice for holding the stop device to a variable positionsubstantially as described.
